Flashing and Testing

Finally i have received the 1st batch of assembled units for the November campaign. And they look great! I need to flash and test each unit with firmware before shipping them, and that will be done ASAP!

I got several comments that it would be a good idea to upload and share the manual online. It will therefore be uploaded to the Github together with the open source files. I will not send any manual in each package.
